KONTAN.CO.ID – LONDON. British medicine regulators have advised people with a significant history of allergies not to get the Pfizer-BioNTech coronavirus vaccine after two people reported serious reactions on the first day of the vaccine launch.
Starting with the elderly and frontline workers, Britain began mass vaccinating its citizens on Tuesday, as part of a global effort that poses one of the biggest logistical challenges in history.
Britain’s National Health Service medical director Stephen Powis said the advice had changed after two NHS workers reported anaphylactoid reactions associated with receiving the vaccine.

“As is common with new vaccines, the UK Medicines and Healthcare Products Administration (MHRA) has recommended for prevention that people with a history of major allergic reactions not receive this vaccine, after two people with a history of allergic reactions Major allergies responded negatively yesterday, “Powis said.
However, it was reported that the two eventually made a good recovery. The MHRA said it would seek more information, and Pfizer and BioNTech said they supported the MHRA investigation.
Last week, the MHRA became the first in the world to approve the vaccine developed by BioNTech and Pfizer, while the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) continue to work with medical data.
“Last night, we saw two case reports of allergic reactions. We know from very extensive clinical trials that this is not a feature,” June Raine, MHRA executive director, told lawmakers.

Pfizer said that people with a history of severe allergic reactions to the vaccine or candidate material were excluded from the end-stage trials, which is reflected in the MHRA’s emergency approval protocol.
The new MHRA guidelines, sent to healthcare professionals, say that a broader segment should not use vaccines. “Anyone with a history of significant allergic reactions to vaccines, drugs, or foods should not receive the Pfizer BioNtech vaccine,” MHRA wrote.
